Convex Lens (उत्तल लेंस) | Class 10 Science – Light | CBSE/NCERT

Aaj hum Convex Lens ko bilkul easy Hinglish me samjhenge ✅ Convex lens centre se thick aur edges se thin hota hai. Isko converging lens bhi kehte hain kyunki ye parallel light rays ko focus (F) par laa kar milata hai. ✅ Important Points (Exam Ready) Convex lens = Converging lens Parallel rays lens se pass hokar principal focus (F) par milti hain. Focal length (f) = Optical centre (O) se focus (F) tak ki distance. Power of lens (P): 𝑃 = 1 𝑓 ( in meter ) P= f(in meter) 1 ​ Unit = Dioptre (D) (Convex lens ki power positive hoti hai) ✅ Image Formation (Quick Rules) Object Infinity par → image F par (real, inverted, small) Object Beyond 2F → image between F and 2F (real, inverted, diminished) Object at 2F → image at 2F (real, inverted, same size) Object between F and 2F → image beyond 2F (real, inverted, enlarged) Object at F → image at infinity Object between O and F → image virtual, erect, enlarged (magnifying glass) 💡 Uses: Magnifying glass, camera, microscope, spectacles (hypermetropia) 📌 Notes + Ray Diagrams + MCQs chahiye?
